Weblog software such as I use to maintain this site works like this: As I post items, the software builds a page of that day's postings arranged from latest to earliest. It also builds the front page which displays the last few days of postings.
Previously, the front page displayed a whole week's worth of postings but I've been posting a lot lately. Seven days of messages made for a long page…too long for folks who are on slow connections. So now the front page only displays four days of postings. To read earlier news items, click on the right arrow at the bottom of the page.
If that doesn't make sense, don't worry. All you have to know is that when you come here, read down and keep clicking the right arrows until you come to messages you've read before.
